MDN JavaScript optional chaining optional computed property name .optionalComputed expression [expression]
💡 Result:
In JavaScript, optional chaining can be used with computed property names using the syntax obj?.[expression] [1][2]. This is referred to as optional dynamic property access [2][3]. The optional chaining operator (?.) allows you to access a property or call a function [4]. If the value on the left-hand side of the operator is null or undefined (nullish), the expression short-circuits and immediately returns undefined instead of throwing a TypeError [4][2]. When using computed property names, the expression inside the brackets [expression] is only evaluated if the object being accessed is not nullish [2]. Examples of the three optional chaining positions include: - Optional static property access: obj?.prop [2][3] - Optional dynamic property access (computed property name): obj?.[expression] [1][2] - Optional function or method call: func?.(...args) [2][3]

Fix the invalid optional calculated-property syntax.
user?.name?[0].toUpperCase() is invalid JavaScript and stops Avatar.jsx from parsing. Use ?.[ for optional calculated-property access. Keep optional chaining before toUpperCase() so missing or empty names still render "?".
Proposed fix
- {user?.name?[0].toUpperCase() || "?"}
+ {user?.name?.[0]?.toUpperCase() || "?"}📝 Committable suggestion
‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.
